Manual Extract: Steering Control

The steering control system utilizes a gear pump and a variable displacement pump powered by the diesel engine. These pumps draw oil from the oil tank and direct it to the priority valve.

When the steering system is inactive, the power steering does not apply any pressure signal to the priority valve, freeing up delivered oil for other attachments. Activation of the steering wheel generates pipe pressure that actuates the priority valve’s switching piston.

Based on the intensity of this pressure signal, the priority valve adjusts the quantity of oil sent to the power steering. The steering mechanism is supported by two internal valves within the power steering, each set to 240 bar (3480 psi). Once the steering cylinder activates, oil flows through the power steering system and returns back to the oil tank via a return filter.

If there is a pump malfunction, a check valve ensures the power steering can still draw oil from the tank, permitting further steering maneuvers.
